Mifl'UFACTURE OF BOOTS AND SHOES.

No Drawing.

To all whom "it may concern;

Be it known that I, Josnr Micunnn, manufacturer, subject of the King 0"Prussia, and "resident of lx'ervenheim, near Kevelaer, in RhenishPrussia, have invented certain new and useful Improvements in theManufacture of Boots and Shoes, of which the following is a full, clear,and exact description.

The invention relates to shoes and boots and particularly to the makingof both the toe and heel-caps, and consists mainly in em ploying forforming the same the upper leather and lining, these parts themselvesbeing stiflened for the purpose at that place only where the cap is tobe formed, by applying a celluloid-solution.

This invention entirely does away with the great disadvantages connectedwith the caps up to now used, which all the means hitherto employed werenot able to remove.

Up to thepresent for shoes and boots requiring stiff caps, therewere'employed always separate bodies of different material, which bodieswere cut out in their special necessary size and shape and then inlaidand secured between the upper leather and the lining at the heels andtoes of boots and shoes, thus forming the stiff caps Therefore, foremploying and applying such caps, not only the material for the separateand special cap bodies was necessary, but also the work of making saidbodies by stamping or cutting them out and forming or molding them, andfurther the adhesive material, such as paste, glue, or the like, and thework for placlng, fixing and securing the special cap bodies at thedesired place between up per leather and lining; Such separate caps wereusually either thick leather caps, or shaped celluloid caps, both ofwhich were very expensive, or ready shaped cardboard caps, or caps ofmaterial coated with paste, the latter of which however were notpreviously finished and stiffened, but, when required were out out ofthe material, coated with the paste and inserted between the upperleather and the lining. But neither the latter stiffener-s, nor thecardboard caps, are proof against perspiration, "armth and wet, butbecome limp in wearing and do not remain elastic, but crease and get outof shape. W'itlr'my new 'invcntion the manufacture of boots and shoeswith perfect caps is very much simplified and rendered cheaper, becauseseparate and special caps are done Specification of Letters Patent.Patented Dec. 13, 1-,910. Application filed February 3, 1903. Serial No.141,746

away with and therefore all the disadvantages ot such avoided.

original employment of a celluloid-solution working upon andnreombuiation with the upper leather and the lining of the shoe and capsfor boots and shoes.

l state that the term celluloid solululoid or one of the varieties ofthe same, some of which are known as xylonite, parkesinc etc., and alsothe ground-material of celluloid orits varieties, z'. e. pyrox lin ornitro-cellulose, dissolved in any suita le liquid, as acetone, aceticacid and the like.

The new process consists in the following: At that place in the bootsand shoes where the caps are to be made, at the heel as well as at thetoes, the upper leather and its lining are plastered at their adjacentsides opposite to each other with the celluloid-solution in suchextension and shape, as is necessary for fiorming the cap, the two partsare laid upon each other with their plastered places together, united inthe usual manner, mounted upon a last, and pressed together, untilthesolution is dried and hardened. Thus the thin materials forming theleather and lining at the said place are stiffened in themselvesand'torin themselves the cap without using special eap pieces or bodiesmade of thick leather, solid celluloid, cardboard, fabric coated withpaste, or the like, such as were hitherto always used for making thecaps.

With this process very thin caps of a very great stiffness andelastidity are produce no ready cut material in the form of the cap andno special stitl'ener between the upper leather and its lining beingused.

that caps of ready cut and )ressed, or molded pieces of solid celluloiare known and used in the art, further I am aware thateelluloid-solution has been made use of for nmnui'actiu'ing caps bycementing together with such solution layers of fabric and then formingspecial cap pieces or bodies from and inserting such cap pieces betweenthe leather and the lining of the shoe. But never up to now has thecelluloid-solution been made use of for stitlening the upper leather andthe lining of boots or shoes to The invention is based upon a new andconsists 111 an improved process for making lion comprises the materialknown as eel- As already stated above,l am quite aware the thus preparedand united fabric-layers caps previously ,used are be immediatelystiffened themselves.

such extent as is necessary for the cap, by plastering the oppositesides of said two parts, (1. the under or inside ot'the upper leatherand the upper side of the lining, with celluloid solution, thus causingthe pores in the leather and lining to he filled up ')y thecelluloid-and thereby the said parts to In this manner the boot or shoeis stiffened to the desired extent at its heel as Wellas at the toe andprovided with a so-called cap without applying and inserting a propercap, 2'. 0., a specially prepared cap-piece or body, such as has beenalways used previously.

Having noW fully described my invention,

. what I claim and desire to secure by Letters Patent, is y The processhereindescribed of providing caps for boots and shoes, wlnch consists 1nstifiening corresponding parts of the upper leather and its lining byplastering them at that part of the boot or shoe where a cap is to beformed, on their adjacent sides opposite each other withcelluloid-solution to such extentand shape; as corresponds to the formof the cap which is to be made thus filling up the pores of the leatherand the lining with celluloid, and then laying the two parts upon eachother with their plastered places together and uniting the same in anyusual manner, and finally mounting the whole-upon a last and pressing ituntil the solution is dried and the whole hardened.

In testimony, that I claim the foregoing as my invention I have signedmy name in presence of two subscribing witnesses;
